S. Korean Shipyard Blast Kills Four

On Friday, four South Korean works at a shipyard in Ulsan, located in southeastern S. Korea, were killed in an explosion, police reported.

Reports indicated that sparks from an oxygen-fuelled cutting machine might be to blame for the fatal blast at Sejin Heavy Industries, a company producing ship components.  At the time of the incident, the four workers were inside the cabin of a 4,200-ton vessel, according to Yonhap news agency. 

Police say an investigation is underway to uncover the cause of the blast that took the lives of the four workers.
